Properly support pushing additional tags on a manifest list
Properly support pushing additional tags on a manifest list

Add a wrapper so that push of a tag doesn't descend the merkle tree
as effectively we are simply pushing the same manifest with a new tag
reference. Also set the ref.name OCI annotation to allow this to work
properly with the containerd remotes/ pusher code.
